fsx(8)

NAME

fsx − file system exerciser

SYNTAX

/usr/field/fsx [ −h ] [ −ofile ] [ −tn ] [ −fpath ] [ −pm ]

DESCRIPTION

The fsx exerciser exercises a file system by spawning up to 250 (the default is 20) processes that create, open, write, close, open, read, validate, close, and unlink a test file. These test files are created in /usr/field (the default) unless the −fpath option is used. The exerciser will run until <CTRLC> or kill -15 pid is sent to the process.

A logfile is made in /usr/field for you to examine and then remove. If there are errors in the logfile, make sure you check the /usr/adm/syserr/syserr.<hostname> file, because that is where the driver and kernel error messages are saved.

OPTIONS

The fsx options are:

−hPrint the help messages for the fsx command.

−ofileSave the output diagnostics in file.

−tnRun time in minutes (n). The default is to run until the process receives a <CTRLC> or a kill -15 pid.

−pmNumber (m) of fsx processes to spawn. The maximum is 250; the default is 20.

−fpath
Path name of directory on file system you wish to test. For example, /mnt or /usr. The default is /usr/field.

EXAMPLES

The following example runs 10 fsx processes on /mnt until the process receives a <CTRLC> or kill -15 pid.

% /usr/field/fsx -p10 -f/mnt

The following example runs 20 fsx processes on /usr/field for 120 minutes in the background.

% /usr/field/fsx -t120 &
